    Ordered 6x3Tb from this seller for 26/each. 4 of them were 100-200TB read and half less of writes, one was 1PB read, and the last one surprisingly a 4TB drive.
    Ordered another BO of 6 for 25/each.

    You need a Raid controller or HBA. The LSI/Avago/Broadcom chip based models are popular here. Read this hardware forum. If you bought the 12G drives like I did you would want a 12G controller which are a bit more expensive. The last 6G cards I bought were pretty cheap and breakout cables are easy to find.

    The LSI chips get hot and need proper cooling.
    Do you have a backplane? rack server? external das? diy white box?
    Depending on your storage solution software/os you may need to flash the card into IT mode.

    There is a good guide for this written by Patrick.
    Link to SAS/SATA Cable guide

    Your HBA likely has the older internal SFF-8087 and you just have drives in a plain diy box.
    This is very common for beginners. Most of my HBA are like this.
    If so, You need SAS to SATA Forward Breakout Cable
    Link to example on Amazon

    The HBA usually has 1 or 2 SFF-8087 and you would need 1 or 2 cables to support 4 or 8 SAS/SATA drives.
    You would need to separtely wire power.

    You could also use an SFF-8087 to SFF-8482 x 4 fanout SAS cable.
    Link to example.
    I use 1 of these in a similar setup and the power molex connector is easy to wire.
